WILLIAM P. SMITH, DE LOS 'ANG-ELES, CALIFORNIA.

on. BURNER;

' Application filed November 18, 1521., Serial No. 516,067.

Be it known that I, VVILIJAM. P. SMITH, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Oil Burners, of which the following is a specification.-

My invention relates to an 'oil burner, and

has for its object the provision of a relatively simple and eflicient burner that may be advantageously employed in boiler furnaces, or wherever it isdesired to generate a relatively high degree of heat by the combustion of liquid hydrocarbon;

' Further objects of my invention are to generally improve upon and simplify the construction of existing types of similar forms of oil burners, to provide a construction that may be easily and cheaply pro duced, to provide simple and efficient means for accurately regulating the flow of vaporized liquid hydrocarbon through the jet orifice of the burner, and further to pro vide an oil burner that maybe readily assemb-led or taken apart thereby facilitating installation, repairs and the cleaning of the device.

through the center of a-boiler furnace and.

showing the same equipped with an oil burner of my improved construction.

Fig. 2 is a vertical section taken through the center of an oil burner of my improved construction.

t Fig. 3 is a horizontal section taken on the line 3--3 of Fig. 2.

Fig. 4 is a transverse section taken approximately on the line 4''4 of Fig. 2.

Referring by numerals to the accompanying drawings which illustrate a practical embodiment of my invention, 10 designates a horizontally disposed boiler, 11 the outlet to the stack, 12 the boiler setting, and 13 the fire box or chamber beneath the boiler.

The main body of my improved burner comprises a substantially rectangular block 15 of metal Within which is formed a circular chamber 15, and applied to the under side of the block 14 and secured thereto in any suitable manner, preferably by means i of cap screws, is a plate 16 in the upper surface of which is formed a longitudinally disposed shallow recess 17. This recess 17 extends beyond one of the end walls 14 of the block 14, and formed in the lower'edge ofthis last mentioned end wall immediately above the outer end portion of the recess 17 is a notch or recess 18, the depth of which gradually decreases toward the outer face of said end wall. j

Arranged for backward and sliding move-- ment within the recess 17 is a plate 19' from the rear end portion of which projects upwardly a pin 20 having its upper end notched or bifurcated in order to receive the grooved rear end portion 21 of an adjusting screw 22, and which latter passes through the end wall of the block 14 opposite the end wall 14*.

Arranged within the chamber 15 in block 14 is a pair of cross partition Walls 23 that are perforated as designated by and these partition walls are retained. against rotary movement within the chamber 15 bypins, such as 25, that depend from the top of the block 14. Leading through the top of the block 14 and into the rear portion of the finger 15 therein, is the forward end of a horizontally disposed tubev section26, the rear end thereof being connected to the rear end of a similar tube section 27, the latter being extended forwardly through the fire box and through the front wall of the boiler setting, and connected to the forward end of said tube section 27 in front of the boiler setting is a steam supply pipe 28 that leads from a suitab-ly'located superheater, and said supply pipe 28 being provided with a regulating valve 29.

Leading into the supply pipe 28 at a point directly in front of the boiler setting is a liquid hydrocarbon supply pipe 30 that is pro'videdwith a suitable regulating valve tion of tube section 27, and this rear end portion is formed into a jet nozzle 32.

It will be understood that the body 14 of the burner is positioned within the fire box of the furnace, preferably at a point below the intermediate or front portion of the boiler 10, and that the rear portions of tube sections 26 and 27 extend rearwardly a substantial distance beyond the body of the burner so that said tube sections lie directly in the path of travel of the flame issuing from the jet opening or orifice 18 at the rear end of said burner.

Regulating valves 29 and 81 are opened to admit superheated steam and liquid bydrocarbon to enter tube section 27, and as said steam and liquid hydrocarbon pass rearwardly through said tube section and thence forwardly through tube section 26, they will be heated to a relatively high degree by the flames from the burner, and as a result the liquid hydrocarbon will be com pletely vaporized, and in such condition will mix with the superheated steam thereby forming a highly combustible vapor, and which latter, after passing through the chamber 15 within block 1* will burn freely as it issues from jet orifice 18. The combustible vapor, in passing through chamber 15 in block 14, Will, of necessity, pass through the perforations 24: in the cross partitions 23, and which action insures a perfect mixture of the vaporized liquid hydrocarbon with the superheated steam, and as the resultant mixture discharges from the jet orifice 18 its flow therethrough may be very accurately regulated and controlled by proper manipulation of screw 22, and which latter when rotated moves plate 19 backwardly or forwardly through channel 17 and consequently varying the width of the discharge end of said jet orifice 18.

An oil burner of my improved construction is comparatively simple, may be easily and cheaply produced, and is very effective in performing its intended functions.

Obviously, oil burners of my improved construction may be advantageously and economically employed for various heating purposes, other than for the generation of steam.

It will be readily understood that minor changes in size, form and construction of the various parts of my improved oil burner may be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

I claim as my invention:

1. An oil burner comprising a body having a chamber formed therein and including a recessed bottom plate, a jet orifice formed in the body through which the gas is discharged from the burner, and a plurality of partitions within the chamber, said partitions being radially disposed and perfo rated, a gas inlet at the top of the chamber arranged to cause the gas admitted to the chamber to pass through the perforations of all said partitions before reaching the jet orifice.

2. An oil burner comprising a hollow body having a chamber therein, an inlet at the top of the chamber, an outlet at one side of the chamber, and partitions within the! chamber, said partitions being perforated and radially disposed.

3. -An oil burner comprising a body having a chamber, formed therein and including a recessed bottom plate, a jet orifice formed in the body through which the gas is discharged from the burner, a plurality of partitions within the chamber, said partitions being radially disposed and perforated, a gas inlet at the top of the chamber arranged to cause the gas admitted to the chamber to pass through the perforations of all said partitions before reaching the jet orifice, and a plate slidable in said recess for controlling the passage of gas from said orifice.

4. An oil burner, comprising a hollow body, a fuel inlet at one side of the body and an outlet at another side of the body, and means within the body for causing the fuel to divide and describe different paths through the body and substantially concentric of the axis thereof before reaching the outlet.

5. An oil burner, comprising a hollow body having a fuel inlet and an outlet, and perforated partitions in the body disposed in planes intersecting the axis of the body and extending radially of the axis, the inlet being disposed in parallelism to the axis and the outlet at right angles thereto.

6. An oil burner comprising a hollow body having a fuel inlet, a fuel outlet and a removable and recessed bottom, foraminous partitions in the body disposed in planes intersecting the axis of the body and extending radially of the body, a notch formed in the body adjacent to the bottom, and a plate slidable on the recessed bottom to control the passage of fuel through said notch.

In testimony whereof I have signed my name to this specification.
